- Deathless Vigor: Add the highest-level necromancy-spell you can cast to your negative hit point total before you die. Additionally, you are only disabled when in less than half your best necromancy spells level's negative hit points.

- Revenant: Once per day when unconscious and carrying an onyx worth 25 gp per level, you automatically create a skeleton/zombie to carry out your wishes/guard you.

- Student of the Dead: If you spend a 15 minutes with a recently deceased corpse, you can exchange your prepared spells. Spontaneous spellcasters can swap a known spell with one from their spell-list.

- Vampiric Spell: This metamagic feat adds +1 to the spell's level and can be applied to any spell with a saving throw fort half/fort negates or will half/ will negates. For any victim who fails the save, you gain 1d4 temporary hit points up to a maximum of the spell's level.

Conclusion:
Editing and formatting are top-notch, I didn't notice any glitches. Layout adheres to a 3-column standard and the pdf has no bookmarks, but needs none at this length. I really liked the 4 new feats, but vampiric spell feels rather under-powered - for an additional spell-level, the restrictions of not stacking hp up to the spell's level felt rather weak to me. Seeing that the feats still are cool and iconic, I'll settle for a final verdict of 4 stars - a good pdf, though vampiric spell needs an upgrade.
